A USA Today/Bank of America Better Money Habits poll of Millennials finds that while they say they have good financial habits, most still worry. They say they're good at living within their means, but many are living paycheck to paycheck. They also say reducing their debt is a priority, but they can't save for emergencies. It doesn't help that, in spite of improved market, wages haven't improved. Nor do rising student loan debt and rent prices help.
